GRAIN-CARDOOR.

SPECIFICATION forming part of Letters Patent No. 289,445, dated December4,1883.` Appiimfion filed Augst 2,1883. (No model.)

To @ZZ whom t may concern:

Be it known that I, FRANCIS POND, a citizen of the United States,residing in Hinsdale, in the county of Du Page and State of Illinois,have invented a new and useful Improvement in Grain-Car Doors, of whichthe following is a specication.

In grain car doors heretofore constructed great difficulty `isfrequently experienced in opening the door when grain or other freightis piled against it, as such doors haveordinarily been so made that theycan only be opened in one particular way.

The object of the present invention is to provide a grain-car door thatmay be opened in a variety of different ways, so that in any exigency itmay be easily opened in some one of the different ways. In the presentinvention the door is hinged at one corner by a two-way hinge to anupright bent rod, which is hinged at top and bottom to the door-casingor side of the car. One of the upper corners of the door is supported bya bent quadrant-shaped rod secured at one end to the back edge of thedoor, near the top, and at its other end to the bottom edge of the door,near the middle therei ner of the casing, and the distance between thestraightor vertical part of the rod and the casing is equal to thethickness of the door, so

that the door, when it is turned on its pivoted corner, may be turnedback between the vertical rod and the casing or side of the car, andalso so that the door may be opened or swung outward,` inwhich case thedoor rests between the vertical rod and the front edgeof the casing. Byreason of the swinging of the bent rod on its pivots the door mayreciprocate back longitudinally far enough to swing past the offset orgrooved casing, in which it rits at its front end. By this ,means itwill be seen the door may be swung vor opened either in- The bent orbitl ward or outward; or it may be raised vertitically upward and thenswung either in' or out around the vertical rod; or its front corner maybe raised and revolved in a vertical plane around its pivoted corner tothe extent of ninety degrees, and then, if desired, swung or turnedaround the vertical rod as a hinge, so that the door may be opened orclosed in a variety of different ways, as may be most convenient.

In the drawings which form a part of this specication, and in whichsimilar letters of reference indicate like parts, Figures l and2 areside elevations of a device embodying :my invention, showing the door indifferent positions. Fig. Bis ahorizontal section, taken just above thequadrant-shaped rod. Fig. 4. is a sectional end view of the car, showingthe door swung outward. Fig. 5 is a side elevation, showing the doorpartially turned on'its pivoted corner. Fig. 6 is a cross-section online 6 6 of Fig. 5, showing the door in position when closed 5 and Fig.7 is an enlarged sectional view of the universal or two-way hinge at thecorner of the door. Figs. 8, 9, and l0 are horizontal sectional views,showing plans .of the door when `standing on its end and swung ,into anumber of different positions,

and Fig. 11 is Va similar view of the door resting on its bottom edge.

In the drawings, A represents the door, B the casing or frame of thecar, and C is the upright bent rod to which the door is swung. The rodC, at its upper end, has a bend or oii` set,`c, equal in length to thethickness of the door, and is pivoted to the frame of the car by theloop o at the interior corner of the doorcasing B.. Ihe lower end of therod C it is preferable not to bend in this manner, but to secure it to athin iiat horizontal metal arm, c, which is secured and pivoted to theframe or floor of the car by the pin c3 at the corner of the casing B.By employing the thin flat arm c2 the corner ofthe door does not requireto be much eut out. l

The lower or pivotal corner, A', of the door is provided with a two-wayhinge consisting of the metallic piece or knuckle D, secured to the doorby suitable screws, which lreceives the pin d, the other end, cZ, ofwhich is aknuckle IOG to receive the upright rod C, upon which it mayslide freely, so that the door may slide up and down on the rod C. Thelower corner of the knuckle or piece D is notched or cut out, as shownat d2, to the thickness of the flat arm c2, so that the lower edge ofthe door will rest fiat upon the door-sill or fioor of the car andpermit of the rod C swinging on its hinges or pivotsc and c.

A rod, F, preferably quadrant-shaped, is secured at one end to the backedge of the door, near its top, and at its other end to the lower edgeofthe door, near its middle, so as to leave suici ent space between therod and the side of the door for the vertical rod C. The ends of thisrod are bent at right angles at e, and should be flattened out andcountersunk in the edges of the door, so as to be flush therewith. Theymay be secured by asingle nail or screw when thus countersunk and bentaround the edges of the door.

The casing B, at the front or free end of the door, is provided withajam or shoulder, b,

for the door to t against, and a projecting facing b', thus forming agroove or guide for this end of the door, as shown in Fig. 3. It may belocked or secured by any ordinary lock or bolt-as, for example, a simplepin, F-passing through the casingand into the edge ofthe door. Theslight sliding or reciprocating motion given to the doorby swinging therod G on its pivots is sufficient to draw the door out from between thecasing B and the facing or flange b', andallow it to swing open ineither direction around the rod Gas a hinge. The door may also belifteddirectly upward, in which case the shoulder b of the casing and thefacing b furnish a guide or way for one end of the door, while the rod Canswers the same purpose for the other end of the door. After' the doorhas been thus raised it may be swung around the rod Casahingein eitherdirection. There is sufficient space between the bent rod C and the doorpost or casing to permit the door to swing freely around said rod,whether the door stands on its end, as shown in dotted lines in Fig. l,0r rests on its bottom edge, as shown in full lines in said figure. Thebent rod C being also pivoted or hinged to the door-casing, the roditself can swing around as the door is swung into different positions,and thus prevent the corner or edge of the door binding against thecasing or door-post, as is illustrated in Figs. 8, 9, and 10.

G is a pivoted projection provided with a turned-up lip, g, and securedto the side of the car by a pivot or pin, for the purpose of supportingor holding the door when it has been thus opened. The support G ispivoted to the side of the car, so that it may be turned out of the wayof the door when it is opened back in other positions than that shown inheavy lines in Fig. 2, and to prevent said sup port being knocked off orinjured when the car is used for handling lumber or other freight thangrain. The quadrantsshaped rod E serves to support or hold the door inits vertical plane when it is being lifted or turned-as, for example, asshown in Fig. 5-and when the door is being swung around the rod C as ahinge, whether it be in its horizontal position, as shown in Figs. l, 2,4, or 6, or in its vertical position, as shown in dotted lines inFig. 1. The bends e, at either extremity of said quadrant-shaped rod,serve as a hinge or knuckle to hinge the upper part of the door to thevertical rod C.

Then the door A is turned vertically, so as to stand or rest on its end,as shown in dotted lines in Fig. l, it maybe swung inward around the rodC, as the lower bent end of the quadrant-rod Eis secured near the bottomedge of the door in the same manner that the upper end of said rod issecured near the end of the door, and, as the combined pin and knuckle del is secured at the lower corner of the door, the door may swinghorizontally, whether it rests on its bottom edge, as shown in solidlines in Fig. l, or stands on its end, as shown in dotted lines in saidligure.

I clai1nl. The combination of the bent upright rod C, pivoted to thecar, and door A, hinged to said rod by a two-way hinge, so that saiddoor may swing open horizontally or turn around said hinge as a centerin a vertical plane, subn stantially as specified.

2. The combination of bent upright rod C with door A, hinged to said rodby a two-way hinge at one corner of said door, and rod E, extendingalong the side of said door, from near its upper corner to its lowerside, and embracing said rod Cv between the same and the door,substantially as specified.

3. The combination, with a grain-car door provided with a two-way hinge,of a rod, E, extending parallel with the side of the door, from near itsupper corner to its lower side, substantially as specified.
